I've been using Seat Concepts seats on various dual sport and supermoto bikes for years now, and they are a must-have upgrade if you're like me and can't sit on the typical OEM seat for very long. On our Honda CRF450RL project bike, I noticed how narrow the stock seat was right off the bat... it's basically the same seat they put on their motocross bikes, which are designed for short rides.
For our project bike, I went with the Seat Concepts Comfort XL seat for the CRF450L / CRF450RL, with the Black Semi Grip (low slip) Top and Red Semi-Grip Sides as the cover material. The seat is about 9" wide at its widest point, compared to about 5" for the stock seat. The seat tapers and gets narrower as it gets closer to tank, so it still allows you to easily move around on the bike. The combination of a wider seating surface, and proprietary foam material, make it much more comfortable than the stock seat, especially on longer rides. I've done several 250+ mile days on Seat Concepts seats and they are a HUGE improvement over pretty much any stock seat.
Cover Material Options:
The CRF450L/RL seats are available in several combinations of materials/color. The covers with the Gripper Top are best for aggressive riding if you really want to be held in place. The covers with the Semi-Grip (Low-Slip) top are slightly less grippy than the Gripper top, but still will hold you in place.... and these seem to be the most popular.
This is a complete and direct bolt-on seat for the bike. You simply take your stock seat off, and put the SC seat in its place, re-using the two stock bolts as mounting hardware. Its literally a 30-60 second install.
Overall I think this is one of the best upgrades you can do for the 2019+ Honda CRF450L / CRF450RL. The stock motocross-syle seat is very narrow and quite un-comfortable. The Seat Concepts Comfort XL seat on the other hand, is wider, and much more comfortable, so you basically forget about the seat and can focus more on your riding. I think the Semi-Grip (Low Slip) Top is probably the best choice for most dual sport/supermoto riders, but if you really like to be held in place, the Gripper Top is the way to go. These seats also look great in the Black/Red color combination.
